Y., A oonPoRATIo or ELAWARE CONTAINER 30am Original application filed December 21, 1826, Serial No. 156,218, now Patent No; 1,693,700, dated December 4, 1928; Divided and this application filed August 27,1927. Serial No. 215,-774.

One of the methods of transporting freight in Wide use at the present time consists in placing the freight in a unit container which may be slid and transferred from one carrier to another without disturbing the individual parcels therein until they have reached their destination, thus materially reducing the amount of handling which would otherwise be necessary in trans-shipping. These containers, however, are bulky and heavy and consequently are difficult to handle. It is therefore the object of this invention to provide means whereby such containers may be readily moved about upon a platform, form housings which may be readily applied to or detached from the container, suitable provision being made for raising the container from the surface upon which it rests so that it may be readilymoved about upon the roll- This application relates specifically to the second embodiment of our invention described in said copending application and for a complete,understanding thereof reference may be had to the following detailed descrip- 1 tion in which reference is made to the accompanying drawings. In the drawings:

Figure 1 is an elevation, partly 1n section,

and showing a practical application of this form of the invention.

Figure 2 is a side elevation of the same showing a pair of the devices illustrated in Figure 1 applied to the side of the container.

In the drawings, a representsacontainer,

provided with blocks or channels a at the bottom and with timber lengths a to keep the container off the floor.

The channels a may be secured to the containers as by bolts and nuts a V 1 On the side of the containers and above each channel piece, are secured suitable bracketsa, between, which and the container, a

liftingarm may bereceived.

The truck member consists of a housing I), provided at its outer side with. a bracket extension 6, which, with the housing, forms a U-shaped recess to receive a roller 6 The roller is mounted on the shaft 12 extending between the two U-members.

Slidably mounted within the housingis a I lifting rod 0 provided with a horizontal hook 0 which engages the channel or block a when raised. Rod 0 has serrations or ratchet elements -0 on its back and an upwardly extending nose 0 which is received in the recess of the bracket a, as previously noted.

To prevent the bogie or truck member from slipping down and disengaging the container when the'latter ismoved over roughand ,uni even floors, provision is made forsecuring the bogie to thefcontainer. Thumb screw mis provided to prevent relative movement between lifting member 0 and housing 6 when the bogie isin operative position. Oo-operating holes 0 and p are provided in the nose of the lifting memberand the bracket a and 1 i to the housing is secured, as by a chain,'-a pin n-which is received in the holes 0 and p and prevents the disengagement of the bogie from the container. After the bogie has been applied and the lifting member raised to the; desired height, the pin n is inserted in the holes 0 and p and the thumb screw m tightened.

' At 5 in housing I) there is pivoted a crank (Z which receives a handle .0? in the usual manner; A pawl e isalso pivoted at b and engages the ratchet teeth 0 to hold the rod 0 in a lifted position. On the lower end of crank d a pawl f'is provided which likewise engages the teeth and through application of suitable force on the lever 03, lifts the rod.,

The elements just described constitutethe parts of any well known type of jack and form no part of this invention.

more, the roller previously described may be Further hook c and nose 0 Will be in such position that, upon raising the rod, the ends Will engage their respectiveseats and lift the container.

The present invention embodies a device which may be used on containers of the commercial form and size to enable them to be readily handled. It is light and strong and can be readily put in use or removed and can be carried by the motor truck to each Warehouse. A further advantage of this type of bogie is that Very little pressure is brought to bear on the side of the'container but is applied underneath Where it is best able to receive the pressure.

Obviously the devices maybe arranged in pairs to form a unitary and stable support for one-side of the container.

No limitation upon the scope ofthe invention is intended-except as indicated in the claim. I

lVhat We claim is:

In attachments for unit containers, a rolling jack comprising a lifting element, a vertic-a1 nose on the upper end of said element, a lug mounted on the container and adapted to receive the end of the nose snugly therewithin, a flange on the lifting element near the bottom thereof, an upwardly projectingend on the flange, a seat on the contamer, a downwardly projecting end on the seat, said seat being adapted to receive the end of the flange in abutment therewith, and means to raise'the lifting means.

This specification signed this 19th day of August, A. D. 1927.
